/**
 * springSession的核心原理
 * 1).@EnableRedisHttpSession导入RedisHttpSessionConfiguration配置
 *      1.给容器中添加了一个组件
 *       SessionRepository=>[RediOperationsRepository]==>redis操作session,session的增删改查
 *      2.SessionRepositoryFilter=>>Filter：session 存储过滤器，每个请求过来都必须经过 filter
 *         1.创建的时候，就自动从容器中获取到了SessionRepository
 *         2.原生的request,response都被包装。SessionRepositoryRequestWrapper,SessionRepositoryResponseWrapper
 *         3.以前获取session.  request.getSession();
 *         4.这里 wrappedRequest.getSession();===>SessionRepository中获取到的。
 *
 *  这里同样是有redis自动续期，也有过期时间
